Abstract:
This article addresses household strategies for coping with perceived tap water quality issues. By using a household survey (n = 581) in Catalonia (Spain) and three models, this article analyses the drivers and motivations behind the installation of in-home water treatment systems, and the use of bottled water for drinking and cooking. The main explanatory factors of the higher consumption of bottled water were the perception of poor tap water quality, the lack of in-home treatment systems, and the presence of children at home. Income did not appear as a significant variable explaining the use of bottled water, unlike in other studies. The presence of in-home treatment systems is related to factors, such as perceived bad water quality, larger households, and single-family housing. Income and housing tenure appeared as explanatory variables only when considering systems requiring some kind of installation: lower incomes or renting a multi-family house reduce the probability of having an in-home water treatment that required installation because of important investments and operating costs, and the space needed in the housing units. In-house water treatment systems may become a solid alternative to bottled water when tap water raises problematic perceptions related to bad taste, odor, or lime presence.

Abstract:
On-site greywater (GW) treatment and reuse is gaining popularity. However, a main point of concern is that inadequate treatment of such water may lead to negative environmental and health effects. Maintenance of single-family home GW systems is usually performed by home owners with limited professional support. Therefore, unless GW systems are reliable, environmental and public health might be compromised. This study is aimed at investigating the reliability of on-site recirculated vertical flow constructed wetlands (RVFCW) in 20 single-family homes. In order to ensure reliability, the failure-tree approach was adopted during the design and construction of the systems. The performance of the systems was monitored for 1.5 years, by evaluating treated GW flow and quality, and by recording all malfunctions and maintenance work. Only 39 failures occurred during this period, of which four caused irrigation with impaired quality GW, while the rest led to no irrigation. The mean time between failures (MTBF) was 305 days; two out of the 20 systems suffered from seven malfunctions (each), while nine systems did not fail at all. Thus, it can be postulated that if on-site GW treatment systems are designed with the right controls, and if scheduled (basic and relatively infrequent) maintenance is performed, GW reuse can be safe to the environment and human health.

Abstract:
A randomised controlled field trial was conducted to evaluate the effectiveness of ceramic drip filters to improve the microbiological quality of drinking water in a low-income community in rural Bolivia. In four rounds of water sampling over five months, 100% of the samples were free of thermotolerant (faecal) coliforms (TTC) compared to an arithmetic mean TTC count of 1517, 406, 167 and 245 among control households which continued to use their customary sources of drinking water. The filter systems produced water that consistently met WHO drinking-water standards despite levels of turbidity that presented a challenge to other low-cost POU treatment methods. The filter systems also demonstrated an ability to maintain the high quality of the treated water against subsequent re-contamination in the home.

Abstract:
The Michigan Safe Drinking Water Act (Act 399) was enacted in 1976 and enables the Michigan Department of Environmental Quality (DEQ) to maintain the state's authority over drinking water in the state. The DEQ also contracts with local health departments to maintain non-community programs in each county. Private water wells throughout the state are clearly the most troublesome for users and regulators. An abundant array of contaminants (e.g., pesticides, metals, etc.) may impact wells without the user's knowledge. Most private wells are only inspected when they are installed and have no further regulatory requirements. With regards to contaminants in public systems, lead is problematic. Irregardless of the source or treatment, the piping infrastructure leading to and inside the home can be a source affecting the quality. Thus, the problem of lead in drinking water can be from the service lines, the pipes inside the home, the solder connecting the pipes, or in some case the treatment chemicals used for disinfection.

Abstract:
This study was conducted to determine whether common water filtration and purification systems bought by consumers and used in the home would remove cyanotoxins from water. Commonly used universal filter housings and filter sizes were utilized to identify filter media that may be effective in the removal of microcystin-LR in deionized water. Results suggest that the efficacy of home filtration devices in removing microcystin-LR varies considerably with the type of device being used. Carbon filters successfully removed microcystin-LR allowing only 0.05–0.3% of the toxin load to pass through the filter. On the other hand, pleated paper and string wound filters allowed >90% of microcystin-LR present in the sample to pass through the filters. Theoretically, the use of carbon home filtration devices tested in this study may provide protection against human exposure to cyanotoxin in addition to protection provided by water treatment methodologies utilized in water treatment facilities. Further studies need to be done to assess the efficacy of home filtration devices for various cyanotoxins and for other filtering conditions such as increased toxin load, the presence of other contaminants in drinking water, and the repetitive use of the same filter over longer time intervals.

Abstract:
Onshore commercial or institutional services for the New Jersey barrier island resorts frequently dispose of wastewater onsite, by percolating septic system effluent to the underlying aquifers. However, to protect the groundwater supplying potable water and brackish wetlands, larger onsite systems must now include advanced treatment to remove nitrates. Effluent produced by a mechanical treatment plant at a new nursing home was improved by percolation through a zoned sand mound disposal bed, but operation of the small but complex plant is expensive. Therefore, another system to remove organics and nitrogen was developed for a shopping center, which was expected to have severe seasonal variations in wastewater quality and quantity. Treatment in a series of in-ground and mounded aerobic and anoxic units provides operational economy and flexibility appropriate to resort area commercial establishments.

Abstract:
A current trend in environmental practices concerns using constructed wetlands for wastewater treatment. The ecological values of wetlands have long been known. Wetland plants aid in the treatment of water pollutants by improving conditions for microorganisms and by acting as a filter to absorb trace metals. Wetlands now are being considered for industrial, municipal, and home wastewater treatment. Constructed wetlands are an economical and environmentally sound alternative for treating wastewater. These constructed “cells” are designed to function like natural wetlands. In constructed wetlands, water flow is distributed evenly among plants in a cell where physical, chemical, and biological reactions take place to reduce organic materials and pollutants. Increasing numbers of environmentally conscious homeowners are installing wetland wastewater treatment systems in their backyards with the aid of licensed engineers. This installation is occurring despite of the lack of educational materials to aid in site selection, selection of appropriate plant materials, and long-term maintenance. Traditional wetland plant species currently are being selected and planted in these sites, and the resulting effect is often an unsightly marsh appearance. With increasingly more homeowners opting for this alternative system, a strong need exists for educational materials directed at this audience. Therefore, educational resources that can provide information to the public regarding the benefits of wetland wastewater systems, while promoting aesthetically pleasing ornamental plant species is needed. A hands-on guide for installing constructed wetlands, a home page on the World Wide Web, and an instructional video currently are being developed at Texas A&M Univ. These technologies will be demonstrated and the values, needs, and opportunities available for the horticultural industry in the area of wetland construction will be discussed.

Abstract:
Для удаления остаточных количеств фармацевтических соединений, присутствующих в питьевой воде, на всех этапах водоподготовки могут применяться разнообразные способы очистки, основанные на различных физико-химических принципах. В работе приведены результаты экспериментального исследования эффективности удаления с помощью бытовой стационарной системы водоочистки остаточных количеств фармацевтических препаратов – антибиотика левомицетина (хлорамфеникола) и стероидного гормона эстрона – из модельного раствора, приготовленного на основе водопроводной воды с добавлением лекарственных препаратов. Показано, что бытовая система водоочистки обладает способностью существенно снижать остаточные концентрации фармацевтических препаратов левомицетина и эстрона на всем протяжении заявленного производителем ресурса. В секторе бытовой водоочистки установки адсорбционного типа по-прежнему остаются наиболее востребованным типом водоочистных систем, обеспечивающих высокую эффективность удаления различных загрязнителей при минимальных капитальных затратах. To remove residual amounts of pharmaceutical compounds present in drinking water, a variety of purification methods based on various physicochemical principles can be used at all stages of water treatment. The paper presents the results of an experimental study of the efficiency of removing residual concentrations of pharmaceuticals – laevomycetin antibiotic (chloramphenicol) and estrone steroid hormone – from a model solution prepared on the basis of tap water with the addition of drugs, using a home fixed water purification system. It is shown that the home water purification system provides for the significant reduction of residual concentrations of chloramphenicol and estrone throughout the service life declared by the manufacturer. In the household water purification sector, adsorption-type units are still the most in-demand type of water purification systems that provide for the high efficiency in removing various pollutants with minimal capital costs.

Abstract:
A randomized controlled trial evaluated the impact of different methods of water agitation on clinical and microbiological outcomes in 31 nursing home residents. Four conditions were tested: a) whirlpool tub, jets on, using standard soap products; b) ultrasound tub, ultrasound on, using the standard soap products; c) ultrasound tub, ultrasound on, using specialized soap and skin conditioner; and d) either tub (randomized), water circulation off, using standard soap products (the control condition). Outcomes of interest included skin microbial flora, water microbial flora, skin condition, time spent bathing, and staff satisfaction. Resident skin condition and skin microbial flora did not differ between the four treatments. The tubs also did not differ in terms of bacterial colonization; however, there was a non-statistically significant trend for the highest counts to occur in whirlpool tubs after being idle overnight. The ultrasound and whirlpool tubs were preferred by staff over the control treatment (still water) in terms of sound and overall suitability. In addition, staff reported that the ultrasound tub using enhanced skin cleansers made bathing residents easier and faster than the same tub using standard cleansers.

Abstract:
In order to make a breakthrough for the acute problem of water shortage in the world, the key words “decentralization and re-use” are very important for new sustainable sanitation systems that will be developed. Therefore, we focused on a new treatments system called “a slanted soil treatment system” which combines a biotoilet system with a domestic grey water treatment system. Because this system is a low cost and compact system, the system can be easily introduced to homes in urban areas or in the suburbs of cities in many developing countries. In this study, we performed on site experiments carried out on Shikoku Island, Japan, for several years. We obtained the following results. The slanted soil treatment system could remove organic pollutants and total nitrogen and total phosphorus in grey water effectively. Furthermore, the system performance became high in the case of the high concentration of the influent water. The nitrification reaction and denitrification reaction were speculated to exist due to aerobic zones and anaerobic zones present in the slanted soil treatment system. The slanted soil treatment system could perform for approximately 3 years with zero maintenance. The plug flow model of 1st order reaction kinetics could describe the reaction in the slanted soil treatment system. However, it is necessary to improve the system to maintain the performance in all seasons.

Arizona Know Your Water.
Today, homeowners have access to several water treatment systems to help control minerals and contaminants and to disinfect their water. Nearly half of the homes in the U.S. have some type of water treatment device. Mistrust of public water utilities, uncertainty over water quality standards, concerns about general health issues and limited understanding about home water treatment systems have all played a role in this increasing demand for home water treatment systems. Private well owners also need to provide safe drinking water for their families and have to make decisions as to how to treat their own water sources to meet this need. However, choosing a water treatment system is no easy task. Depending of the volume of water and degree of contamination, the homeowner should consider professional assistance in selecting and installing well water treatment systems. The process of selection is often confounded by incomplete or misleading information about water quality, treatment options, and costs. The following paragraphs outline the major well water treatment options. Further details on types, uses (point of use) and costs of these home water treatment systems are provided in the Arizona Know Your Water booklet. Additional information about Arizonas water sources that can help private well owners make decisions about home water treatment options, can be found in Arizona Well Owners Guide to Water Supply booklet (see references section).

The conventional on-site household wastewater treatment system is known as the septic tank and absorption (leach) field. Local soil conditions; type, depth, texture and permeability all contribute to how well wastewater is treated as it moves toward groundwater. Soil conditions in parts of Arizona are not suitable for absorption fields, so alternative disposal systems are necessary. This article provides information on alternative disposal systems, the septic tank-mound system, and includes the description of the system, its background, where it should be used, and the cost and time consideration.

Abstract:
This work encompasses the study of a novel thermal driven desalination system to accomplish full separation of water and solute. This process advantageous over other process because it involves zero recirculation and zero liquid discharge, thus having minimum environmental impact. Since this system provides full separation, salts and other valuable products can be obtained in addition to pure water. This system can operate at high energy efficiencies using medium temperature heat source like industrial reject or solar cells. This plant consists of two technologies, the full separation and multi effect distillation which when integrated together 8ive us water and salt separately. Three different configuration of the FS-MED system have been presented, naming concurrent feed, variable feed, and counter current feed. They vary depending on their flow and feed distribution. Numerical procedure has been developed to solve the energy and mass balance equation for steady state condition has been presented.

Abstract:
On-site treatment (home and community composting) of organic waste (OW) reduces cost and environmental issues as opposed to centralized facilities and landfilling. By 2025, such on-site practices could reduce costs and greenhouse gas emissions (GGE) by 50 and 40 %, respectively, and save land as compared to maintaining landfilling practices. However, the shift of municipal solid waste (MSW) management systems from landfill disposal to resource recovery requires technological input, population participation and compost quality assurance. The composting process and quality of composted product depends on the initial compost mixture formulation, design type and management practices of home composting systems (HC). A project was therefore conducted both in the laboratory and in the field, to establish a home composter design and compost formula, which favours the best organic waste decomposition. The results indicated that home composter design is important: perforations must be concentrated at the top and bottom to provide an aeration level equivalent to that of a ground pile. Such home composters can reach thermophilic temperatures when fed at least 10 kg (week)-1 of organic waste with a dry matter content over 15 % (half yard trimmings and half food waste). The compost produced generally offers acceptable levels of polycyclic aromatic hydrocarbons (PAHs) and heavy metals, but residents must be careful in applying the right amount of garden herbicides. The total GGE from home composters were found to be equivalent to that of centralized composting facilities but eliminate the need to spend energy equivalent to 50 kg CO2-eq (tonne wet waste)-1 for handling and processing.
Le traitement des matières résiduelles organiques (MRO) sur place (centres communautaires de compostage et composteurs maison) est une approche qui réduit les coûts de manipulation et de procédé associés aux centres régionaux de compostage et à l'enfouissement. D'ici 2025 et comparativement à l'enfouissement, cette approche pourrait diminuer les coûts de traitement et les émissions de gaz à effet de serre (GES) de 50 et 40 %, respectivement. D'autre part, la diversion et le recyclage des MRO exigent des connaissances techniques et la participation des gens pour assurer la qualité sanitaire du produit, qui dépend du mélange initial, et de la conception du composteur maison ainsi que de sa gestion. Un projet fut donc réalisé en laboratoire et sur le terrain, dans le but de déterminer les critères de conception des composteurs maison et la formulation du mélange initial qui favorisent la décomposition et la stabilisation des MRO traitées. Les résultats ont démontré que la conception du composteur maison est importante, surtout en ce qui concerne l'emplacement des ouvertures qui, quand concentrées dans le haut et le bas, favorisent l'aération par convection. Cette configuration d'ouvertures fait en sorte que le composteur peut atteindre des température thermophiles, semblables aux amas au sol, s'il est chargé de plus de 10 kg (semaine)-1 de MRO possédant une matière sèche de plus de 15 % (moitié résidus de jardin et résidus de table). Le compost produit par résident est généralement propre, avec de faibles teneurs en hydrocarbures aromatique polycyclique (HAP) et en métaux lourds, à la condition d'appliquer des herbicides jardins en quantités raisonnables. Comparativement aux centres régionaux de compostage, les composteurs maison générent la même quantité de gaz à effet de serre (GES) mais font économiser 50 kg de CO2-équ. (tonne de matières résiduelles humides compostées)-1 en tant qu'énergie de manipulation et de procédé.

Abstract:
In today’s world, it has become ever more important to design homes and buildings with considerations that will reduce the total energy requirement and reliance on fossil fuels. Energy conservation is the first important consideration. The construction and appliance components that reduce energy consumption will be presented. Various systems are being included in the design of this off-grid 100% renewable home. The home will incorporate: passive solar design; solar hot water for radiant heat and domestic hot water; woodburning heat with backup hot water coils for domestic hot water and radiant heat; a hybrid electric system with PV and windmill sources and backup diesel generator (modified to use vegetable oil); a rainwater collection system; a graywater treatment system and blackwater treatment. The heating and air conditioning system combines the efficiency of radiant heat with evaluated tube solar hot water technology. A heating coil is incorporated in a masonry heater as the backup. The sizing considerations of the systems are discussed along with the description of methods to discharge excess hot water. Passive solar building design has been a focal point of the home. The heat gain has been considered as the heating system has been designed. The domestic hot water is discussed to compare the demand vs. production of hot water vs. storage. The practices of the homeowner to minimize the need for air conditioning and the design features that improve the conditioning of the air in the summer are presented. The integration of electrical generation will utilize PV, windmill and diesel generator backup (that will be converted to vegetable oil). This combination is used to take benefit of the wind potential while there are periods of little or no electricity generated from the PV system. The size of the systems has been optimized to balance the cost of production vs. storage. The sizing criteria are presented with the optimization calculations for each of the systems. The system design of a rainwater collection system is presented describing the rain water available, the size of the collection area, and the storage capacity. Equipment considerations are discussed with pre and post storage treatment of collected water. A graywater treatment system is designed to take advantage of the passive solar orientation of the home. The system incorporates graywater management practices, sizing of filtration and discussion of placement of components of the system. A blackwater system is also incorporated in the design of the home. The considerations of various systems are presented along with the sizing and utility requirements. The effective design of a 100% off-grid renewable home must first consider the efficient use of all energy. Secondly, the integration of systems is complex and requires the flexibility of the operations of the systems to produce a range of potential capacity to ensure comfort. The systems incorporated in this design are automated to an extent that is practical, however, monitoring of the systems must be conducted to ensure proper operation.

Abstract:
Desalination of high salinity water is an effective way of improving the aesthetic quality of drinking water and has been demonstrated to be a characteristic valued by consumers. Across India, 60% of the groundwater, the primary water source for millions, is brackish or contains a high salt content with total dissolved solids (TDS) ranging from 500 parts per million (ppm) to 3,000ppm. The government does not provide sufficient desalination treatment before the water reaches the tap of a consumer. Therefore consumers have turned to in-home desalination. However, current products are either expensive or have low recovery, product water output per untreated feed water, (∼30%) wasting water resources. Electrodialysis (ED) is a promising technology that desalinates water while maintaining higher recovery (up to 95%) compared to existing consumer reverse osmosis (RO) products. This paper first explores the in-home desalination market to determine critical design requirements for an in-home ED system. A model was then used to evaluate and optimize the performance of an ED stack at this scale and designated salinity range. Additionally, testing was conducted in order to validate the model and demonstrate feasibility. Finally, cost estimates of the proposed in-home ED system and product design concept are presented. The results of this work identified a system design that provides consumers with up to 80% recovery of feed water with cost and size competitive to currently available in-home RO products.

Abstract:
Decentralized water treatment consists of a variety of water treatment techniques for dwellings, industrial facilities, homes, and businesses independent of the power grid. According to the United States Geological Survey, brackish groundwater is abundant in the southwestern states including California; hence it can potentially be considered a new source for California’s water portfolio. Most of membrane-based desalination technologies (e.g. reverse osmosis) have high energy demand and cost. Using renewable energy (mostly solar photovoltaics) in concert with membrane-based water desalination can be utilized to develop decentralized and off-grid brackish water desalination systems especially for remote and rural regions. In this paper, the results of a case study on decentralized off-grid brackish water system have been presented and discussed. The system utilizes a high pressure pump that can provide a feed flow rate of 2.2 gpm of at 140 psi. The system is run by solar photovoltaic panels through a battery bank. The results of the study show that the system is capable of treating brackish water at a salt rejection rate of more than 97.5% and a recovery rate up to 80%.

Abstract:
Wastewater treatment plants (WWTPs) are a significant energy consumer, yet there are several opportunities of implementing on-site power generation systems. Within the treatment process, the high flow rate of effluent is produced and discharged to a nearby water body by gravity. Thus, hydro turbines can be utilized to generate power in such application due to a difference in elevation and high flow rate. This paper presents a case study of introducing a hydro turbine in wastewater treatment plant in Wisconsin and evaluating the power output in addition to determining the energy savings. The wastewater treatment plant considered in this study has an effluent flow rate of 190 MGD (million gallons per day) and elevation difference of 3 meters (10 feet) between the final stage of treatment and the discharge point. Based on the aforementioned parameters; hubless rim-drive Kaplan type hydro turbine (RDT) is the optimal choice to be used in such application. The RDT is designed and optimized by using in-house code. A computational fluid dynamics (CFD) software is applied to evaluate the performance of the proposed model, and the system is simulated through HOMER software to validate the results generated by the CFD. The expected savings is estimated to be 1,564 MWh/year.

Full text
Abstract:
Abstract Effective zonal isolation within a layered reservoir in the Gulf of Mexico is a necessity to meet regulations for stacked reservoirs and to maximize total recoverables. Effective zonal isolation also ensures maximum production is achieved via a high-pressure proppant fracture treatment. A primary cement operation of a 10 1/8" production liner (within a 12 ¼" drilled hole section) was challenging due to a combination of high equivalent circulation density (ECD) and potential losses across a layered GOM reservoir. One layer had potential and significant depletion up to 8,000 psi. Critical well parameter considerations were: maintaining the liner burst of 18,200 psi, maximizing rotation and reciprocation capability of the liner, minimizing the impact on circulation and ECD, and ensuring compatibility with the mud systems. Following careful job planning, including the analysis of caliper data from logging while drilling (LWD) for the optimum placement, two metal expandable packers (MEPs) were installed on the 10 1/8" liner. The MEPs were positioned to straddle the highly depleted layer (one above and one below) in the 12 ¼" open hole section. The liner was deployed, and the cement operation was executed with minimal ECD impact from the inclusion of the MEPs. Surface pressure was applied to create sufficient differential pressure across the 10 1/8" liner wall to hydraulically expand the MEPs quickly under full surface control. This paper covers the qualification, planning, and deployment of MEPs to provide cement assurance (CA) for zonal isolation and improve the effectiveness of contingency cement squeezes. Though this technology has been used in other regions for several years, this was the first deployment in the Gulf of Mexico (GOM). The solution improved the probability of success of the primary cement job, negating the requirement for a remedial cement squeeze. The decision to run MEPs was based on the estimated cost savings of 3.5 million USD for remedial squeeze operations, a value proposition that did not account for the net present value (NPV) gain, due to improved fracture placement, compared to the case of poor cement isolation.

Abstract:
In stormy weather on January 2, 1997, the Russian tanker NAKHODKA broke up at midship into two parts in the Sea of Japan just off the Japanese coast. The recovery operation was hampered by high waves, and the most serious problem was the lack of equipment capable of recovering the spilled oil in stormy weather. In 1998, in response to this accident, the Association for Structural Improvement of the Shipbuilding Industry (ASIS) initiated a three-year research and development project on large-scale recovery systems for collecting highly viscous oil with a minimum kinematic viscosity of 100,000 centi-stokes under severe sea conditions. This paper focuses on the design and evaluation of a newly developed oil skimmer system suitable for the recovery of highly viscous spilled oil emulsified under rough sea states. The oil skimmer system is composed of a float, pump, hose, oil/water separator, etc. The basic design of the oil skimming and treatment system has been completed incorporating the wave-response technology, highly viscous oil suction technology and highly viscous oil collection technology. Furthermore, synthesized model experiment was carried out in a water tank and oil basin using a large-scale model of a developed oil skimming system to acquire the performance data on the constituent technologies and to confirm synthetic function as an oil skimming and treatment system.

Protocol for Monitoring Fish Communities in Small Streams in the Heartland Inventory and Monitoring Network. National Park Service, April 2021. http://dx.doi.org/10.36967/nrr-2284726.

Full text
Abstract:
Fish communities are an important component of aquatic systems and are good bioindicators of ecosystem health. Land use changes in the Midwest have caused sedimentation, erosion, and nutrient loading that degrades and fragments habitat and impairs water quality. Because most small wadeable streams in the Heartland Inventory and Monitoring Network (HTLN) have a relatively small area of their watersheds located within park boundaries, these streams are at risk of degradation due to adjacent land use practices and other anthropogenic disturbances. Shifts in the physical and chemical properties of aquatic systems have a dramatic effect on the biotic community. The federally endangered Topeka shiner (Notropis topeka) and other native fishes have declined in population size due to habitat degradation and fragmentation in Midwest streams. By protecting portions of streams on publicly owned lands, national parks may offer refuges for threatened or endangered species and species of conservation concern, as well as other native species. This protocol describes the background, history, justification, methodology, data analysis and data management for long-term fish community monitoring of wadeable streams within nine HTLN parks: Effigy Mounds National Monument (EFMO), George Washington Carver National Monument (GWCA), Herbert Hoover National Historic Site (HEHO), Homestead National Monument of America (HOME), Hot Springs National Park (HOSP), Pea Ridge National Military Park (PERI), Pipestone National Monument (PIPE), Tallgrass Prairie National Preserve (TAPR), and Wilson's Creek national Battlefield (WICR). The objectives of this protocol are to determine the status and long-term trends in fish richness, diversity, abundance, and community composition in small wadeable streams within these nine parks and correlate the long-term community data to overall water quality and habitat condition (DeBacker et al. 2005).
